worldToLocal Method

• Convert a world point to point within the underlying mapped sphere space.
  • In the sphere space, an xyz (vector from origin) with magnitude equal to 1 is ON the sphere (hence its world image is ON the ellipsoid)
  • In the sphere space, an xyz (vector from origin) with magnitude less than 1 is INSIDE the sphere (hence its world image is INSIDE the ellipsoid)
  • In the sphere space, an xyz (vector from origin) with magnitude greater than 1 is OUTSIDE the sphere (hence its world image is OUTSIDE the ellipsoid)
• This is undefined in the highly unusual case that the ellipsoid frame is singular.
